Abstract

A statistical study of filament and prominence disappearances is described in this paper. A nearly complete set of Big Bear Solar Observatory Hα full disk images observed between January 1997 and June 1999 is searched for filament and prominence disappearances. A list of 431 filament and prominence disappearance events is compiled. Comparison of these data with those from LASCO aboard Solar and Heliospheric Observatory (SOHO) is made to obtain the relationship between CMEs and filament disappearances. Result shows that most of filament disappearances seem to have no corresponding CME events. Even for the limb events, only 30% filament disappearances are associated with CMEs. The possible explanations are discussed in the paper.
